Hamburg is (apparently) famous for its hot chocolate. However, after a recent visit, it became apparent that this is in fact a euphemism for fucking someone over. Below is the basic recipe, though there are numerous regional variants from within the greater Hamburg area:-

Take one large quantity of shit. Preferably the cumulative output of 15 shits, taken at regular intervals over the course of 3 days. Blend and add urine as necessary (in order to thin the consistency). Simmer over a low heat for at least 30 mins. Season to taste. Serve topped with a generous helping of creamy semen. Then force your guests to pay 340 euros for it, despite them not having asked for it in the first place.
